How to fix Error 69845 in Disk Utility?

It is impossible to run a Samsung QVO 870 8 TB on Monterey. I tried all file system types, APFS and HFS+ first, it works for a while, then suddenly the disk may no longer be mounted. This is indicated by error messages such as "Could not mount “Manual Bkup 8TB”. (com.apple.DiskManagement.disenter error 49244.)"Using Disk Utility's First Aid is ending in "File system verify or repair failed. : (-69845)". I tried all other forum/discussion.apple.com suggestions I found, but nothing helped. There must be a severe bug in the File System handling of newer macOS versions. The disk I'm trying is the 2nd one, the first I already returned. I tried on an MBP16 in 2019 and an iMac 5K in Late 2015, both running Monterey 12.2.1.
